20BD077A0NYNAND1

The 20BD077A0NYNAND1 from Allen Bradley's PowerFlex 700 series is an advanced AC drive offering extensive capabilities for industrial applications. Rated for 480V AC in a 3-phase system and running at 60 Hz, it is designed to enhance performance while handling a continuous output of up to 77 amps at a nominal bus voltage of 648V DC.

This drive can manage significant output currents, with heavy-duty operations allowing 98 amps for one-minute durations and up to 130 amps for three seconds. Embedded feedback via a 12V/5V encoder supports precision motor control, while the underscored logic features include a ride-thru capability of 0.5 seconds minimum, typically around 2 seconds.

Operationally efficient up to a maximum altitude of 1000 meters (about 3300 feet) without performance derating, it is built to perform in diverse conditions, with maximum operating temperature rated at 50 °C. It accommodates a broad humidity range from 5% to 95% and includes an AC input undervoltage trip set for 280V AC. The sound level produced by the unit, at a 190 CFM fan velocity, remains at a manageable 59 dB, confirming its suitability for noise-sensitive environments. Carrier frequency settings of 2, 4, 8, and 10 kHz offer flexibility, with a standard operating performance particularly noted at 4 kHz. Digital input latency spans from 9.2 ms during stop signals to 16.0 ms when initiating start signals, ensuring responsive motor operation within the System Variable Control (SVC) architecture.
